Add a can of GM Engine Oil Supplement (EOS) to the break-in oil, and to the first oil change. Get it at the local Chevy dealer.

You camshaft is the old 3896962 hydraulic cam, used in 350hp 350 Corvettes (L-46 engines) in '69 & '70, and in mid-'70s Z-28's (L-82 engine). The part number may have been superceded, but it's the same piece. Duration at .050" is 224*, intake lift is .450", exhaust lift is .460", and lobe separation is 114".

It's probably a little too much cam for the 8.5:1 compression ratio, but it'll run OK. I have the home-made version, a '72 L-48 350 with that cam installed. Won't ping on regular unless I forcibly lug it, but it's not what I'd call real strong down low.
